Question
App Platform inaccessible from certain DNS services

Asked by LittleBlueCrab
I have an app that’s running on an app platform server. It has worked fine for the past 3 months, but all of a sudden it cannot be accessed when using some DNS services. The majority of people who need it can access it, but some users couldn’t. It kept returning net::ERR_CONNECTION_REFUSED whenever a request was sent. When they changed their DNS service to google public they were able to access it. This makes me think it’s a problem with the dynamic IP syncing across DNS services. I don’t have a very good understanding of how dynamic IP addresses or DNS services work. The server currently uses the default domain given by digitalocean.

Hi there,
As you are seeing
net::ERR_CONNECTION_REFUSED, what I could suggest is running a traceroute or an mtr from one of the machines that is unable to connect. That way you will be able to see where the connection is being dropped at exactly.Feel free to share the output of the mtr here so I could try to advise you further.
Best,
Bobby
